In such case, the oil llow is restricted to the capillary channcls in thc i'ccding wick, and the very naturiof thcsc channcls restricts thc amountof oil which :an pass through thc opening, to r lativcly small quantity. prcvcnt ing the flooding ol' the hcar inc during the filling operation The amount of oil which ted to the hoax-inc dcpcnds upon the size of the feeding wick l9 and upon the height of the oil lcvcl at tho {cc-ding cnd oi the oil rcserroir the latter hcing dctcrniinel l by the highe t level of the opcning 1.3, i. c. by the level of the edge Ql of the opening around which the air liuhhlcs must pass to permit morc oil to pass from tho rcscrvoir to the lubricating; chamber.
